For a Layer 2 physical interface (an Ethernet interface works at Layer 2 mode by default): If its physical status indicated by the current state field displays up, its protocol status indicated by the Line protocol current state field displays up.To enable the interface to go up, run the undo shutdown command in the interface view. In the preceding command output, the physical status of GE0/0/12 is Administratively DOWN, indicating that the shutdown command has been run on the interface. Output peak rate 15184 bits/sec, Record time: 17:45:05 Input peak rate 15184 bits/sec, Record time: 17:45:05 Last 300 seconds output rate 96 bits/sec, 0 packets/sec
